Method and system for reconfigurable channel coding

#The present invention relates, in general, to channel coding operations, and more particularly to reconfigurable channel coding operations to accommodate various wireless communication standards.

#The use of cellular telephones in today's society has become widespread. While facilitating communication in a myriad of environments, the various existing and emerging wireless standards inhibit the ability to utilize a single device across the standards and platforms. The inability to have cross-platform coverage in a single device is due in large part to the inability to provide a hardware solution that can be adapted to varying standards.

#For example, in terms of the channel coding operations that are necessary, existing and emerging wireless standards utilize myriad error mitigation techniques to operate in a hostile channel environment. Existing standards utilize two levels of coding plus block interleaving to address both single error and burst error phenomena. Group codes are used for the outer codes, and convolutional codes are used for the inner codes of the various concatenated coding schemes. No two standards employ the same combination. Additionally, certain standards employ encryption to offer a degree of privacy and security.
